**Core Concept**
The tip of the tongue is innervated by the lingual nerve, a branch of the mandibular division of the trigeminal nerve (cranial nerve V3). The lingual nerve carries sensory fibers responsible for taste, touch, and proprioception from the anterior two-thirds of the tongue.

**Why the Correct Answer is Right**
The tip of the tongue, being part of the anterior two-thirds, drains into the lingual veins, which ultimately empty into the internal jugular vein through the common facial vein. This is due to the venous drainage of the tongue, where the anterior two-thirds drain into the facial vein and the posterior one-third drain into the lingual vein, which then empties into the internal jugular vein.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not mentioned in the context of tongue venous drainage.
* **Option B:** This option is incorrect as it does not pertain to the venous drainage of the tongue.
* **Option C:** This option is also incorrect as it is not relevant to the venous drainage of the tongue.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the anterior two-thirds of the tongue are innervated by the lingual nerve, while the posterior one-third is innervated by the glossopharyngeal nerve (cranial nerve IX). This distinction is crucial in diagnosing conditions such as taste disorders.

**Correct Answer:** D
